     linprocfs -- Linux process file system


     linproc	     /compat/linux/proc      linprocfs	     rw 0 0


     The Linux process file system, or linprocfs, emulates a subset of Linux'
     process file system and is required for the complete operation of some
     Linux binaries.

     The linprocfs provides a two-level view of process space.	At the highest
     level, processes themselves are named, according to their process ids in
     decimal, with no leading zeros.  There is also a special node called self
     which always refers to the process making the lookup request.

     Each node is a directory containing several files:

     exe     A reference to the vnode from which the process text was read.
	     This can be used to gain access to the process' symbol table, or
	     to start another copy of the process.

     mem     The complete virtual memory image of the process.	Only those
	     addresses which exist in the process can be accessed.  Reads and
	     writes to this file modify the process.  Writes to the text seg-
	     ment remain private to the process.

     Each node is owned by the process's user, and belongs to that user's pri-
     mary group, except for the mem node, which belongs to the kmem group.


     /compat/linux/proc 	      The normal mount point for the
     /compat/linux/proc/cpuinfo       CPU vendor and model information in
				      human-readable form.
     /compat/linux/proc/meminfo       System memory information in human-read-
				      able form.
     /compat/linux/proc/pid	      A directory containing process informa-
				      tion for process pid.
     /compat/linux/proc/self	      A directory containing process informa-
				      tion for the current process.
     /compat/linux/proc/self/exe      The executable image for the current
     /compat/linux/proc/self/mem      The complete virtual address space of
				      the current process.

     The linprocfs was derived from procfs by Pierre Beyssac.  This manual
     page was written by Dag-Erling Smorgrav, based on the procfs(5) manual
     page by Garrett Wollman.


     The linprocfs first appeared in FreeBSD 4.0.
